If no closed-captions are detected at the input, this feature will effectively become a CGMS generator.
•
When OFF, any incoming CGMS information is passed through untouched.
Insertion: Use the pulldown to turn insertion ON or OFF.
•
When ON, information is inserted according to the selection made in the CGMS-A pulldown. Any incoming
information is overwritten.
•
When OFF, any incoming copy/distribution information is passed through untouched.
CGMS-A options:
•
Copying permitted
•
No more copies
•
One copy permitted
•
No copy permitted
Redistribution Control Descriptor: select this checkbox to force the RCD bit found within the CGMS XDS packet to 1.
For a full description of CGMS control and its purpose, refer to the CEA-608 standard.
5.4.4.5 Meta / Teletext sub-tab
In
50 Hz operation only
, incoming teletext on SD signals
can be converted to OP-47 and inserted in the HD output.
This panel configures this functionality.
SD inputs
– incoming SD Teletext waveforms conforming to
the ETSI EN 300 706 standard are converted to OP-47
packets and inserted in the outgoing HD signal.
•
The
Incoming Teletext Presence
indicators 7 to 22
indicate the SD lines where teletext data, conforming
to ETSI EN 300 706, has been detected.
•
Use the checkboxes in the
Teletext to OP-47 Selection
area to choose the lines whose teletext information will
be converted to OP-47 and inserted in the HD output.
The insertion mode pulldown offers two modes of operation:
•
OFF – no teletext packets will be inserted as OP-47 at
the output
•
AUTO – the incoming teletext from the lines selected in the
Teletext to OP-47 Selection
checkboxes above the
pulldown will be converted to OP-47 packets, and inserted in the outgoing HD signal, in the line selected in the
Insertion Line
pulldown.
HD Inputs
– incoming teletext (OP-47) is passed through to the output as received (PASS mode).
•
The presence indicators 7 to 22 represent SD line number data detected in any incoming OP-47 packet. For
example, if presence indicators 8 and 10 are turned on, this indicates detected OP-47 data is carrying teletext
data derived from (or targeted for) SD lines 8 and 10.
